Letters Patent No. 84,913, dated December 15, 1868. I

The Schedule referred to in these Letters Patent and making part of the same.

To all whom fit 'may concern.-

Be it known that I, S. M. SHERMAN, of Fort Dodge, in the county of Webster, and State of Iowa, have invented new and useful Improvements in`Window-Blinds; and I do hereby declare that the following is a full and exact description of the same, reference' being had to the accompanying drawings, and to the letters of reference marked thereon. i

This invention relates to window-blinds, and consists mainly in the manner of hanging the slats, and in certain novel devices for operating them, the details of which will be fully described hereinafter.

In the drawings- Figure 1 is a front elevation of a window with my improved attachment;

Figure 2, a perspective View, showing one method of attaching the blind-rod to the slats;

Figure 3 is a perspective view, showing my invention as applied to inside shutters;

Figures et and 5 are sectional views through aJ-x, g. l; and

Figures 6 and 7 are plan views ofthe end-clamps a c.

To enable those skilled in the art to which my invention appertains, to make and use the same, I Awill now proceed to describe fully the details of construction and manner of operation.

A represents the frame of a blind, constructed in theh iiom'each other. The former, c, being intended only to form a bearing-surface for the journal, is more simple than the latter, a', which not only forms the bearingsnrface, but is `also used as a lever to move the slats, when desired'. They each, however, are constructed of a single piece of metal, which is cut in the proper shape, and afterwards bent.

The appearance ofthe slats, when complete and in position, is clearly shown in fig. 1.

B represents the blind-rod, which, in my improved arrangement, I placeby the. side of the slats, as shown in iig. l, instead of behind them.

To the side of this rod are attached, in any suitable manner, the lever-ends of the clamps a. By moving the rod in the ordinary way, the blinds are adj usted as desired.

It will be observed that when the slats are open, the

rod does not project beyond them, by which arrangement all danger of striking the-window-sash is avoided.

When the slats are closed, the rod rests in a recess in the frame, so that in both positions it projectsmuch less from the blind than when arranged -in the ordinary manner. I

c represents a rod or bar, attached to the upper end of the blind-rod, the lower end of which is pivoted to the crank or cam al, as shown.

This cam is securely attached to the frame A, in such manner as to swing freely, and is constructed with a square socket, as shown.

By inserting a suitable key into this socket, the cam may be turned, and the blind operated, as desired.

By making a suitable opening in the window-sash, in line with this socket, the slats may be operated'from the inside of the room with perfect ease.

It is only necessary that the key extend through the sash, and be provided with a suitable knob or handle, for the purpose of operating it.

The outer end 'of the key may be made ofa square, tapering form, by which means it is readily inserted into the socket.

The blinds also may be opened, when desired, without drawing out the key, as the latter readily becomes disengaged.

The key for operating the upper set of slats is arranged in the same way. .It passes through the upper sash, over the meeting-rail, in which position it also serves as a secure window-fastening..

Some of the advantages of the construction and arrangement described are as follows: j

The journal or'bearing being upon the inside of the slats, their weight presses outward and downward, by which means they naturally remain closed, and cannot be opened by a gust of wind, as is frequentiy done with the ordinary. slats. The blind-rod is out of the way, and all danger of striking the sash avoided. .The blinds are more durable, although made of a less amount of material. They are easily operated without raising the window.

My devices for operating the slats may be easily applied to the ordinary blind, as shown in g. 1.

c represents the cam.

c, the connecting-link.

c2, a bell-crank.

ci, the bar attached to the blind-rod.

By moving the cam, the slats are operated as before.

In g. 2, lanother method of operating the ordinary slats is shown.

The rod h, instead of being attached by staples in the middle, is placed at the side, the attachment being made by a sheet-metal-clamp, 71.', as shown.

This is much more substantial than the ordinary arrangement, and puts the rod entirely out of the way.

A still further modification of the described arrangement is shown in lig. 3, which is intended for inside blinds.

The slats, .inthis case, are perpendicular. They are used.

constructed,- however, inail respects like the slats shown in-g. 1, excepting that instead of a rod, links, k, are

The cam, also, is provided With a square projection, and the socket is in the key.

These differences, however, are not material, and do not aiect at al1 the operation ofthe slats.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Patent of the United States, is-

1. The slats A', provided with clamps a a', as and for the purpose described.

2. The slats A', having the clamps a af, in combinar tion with rod B, bar c, and cam ll, the whole being cong purpose set forth.

3. The cam e and ,bar e3, with or without the yintermediate' conneotions'e e2, when arranged as described,'

in connection, either with the rod of a blind ofthe usual construction, or a rod attached to the slats by the clamps h', as set forth.

This specification signed and witnessed, this 21st day of September, 1 868.
